Specifications

KBr beamsplitter with Germanium coating for 1.33-18 microns range ( T/R=50/50 +/-20%) + compensator. Custom coating shape.

IR beamsplitters: KBr beamsplitters with Ge coating, CaF2, ZnSe beamsplitters.

Alkor produce KBr beamsplitter with Ge coating for 1.33-18 microns range ( T/R=50/50 /-20%). We make round and square KBr beamsplitters according to customer's specifications. Moisture protective coating (Parylene analog) can be applied on beamsplitter and compensator upon request. We can produce custom shape Germanium coating - it could be very useful for adjusting optics in visible spectrum. All KBr beamsplitters carefully packaged into plastic boxes with silicagel and sealed with special moisture protective film.

 

We are experts in beamsplitters for more than 20 years. Our beamsplitters are widely used in spectrometers for petrolium testing, fuel testing, mining industry and many application all over the world.

Also we offer plate and cube beamsplitters for unpolarized, polarized P or polarized S light. These beamsplitters are coated with special dielectric coatings that transmit a specified percentage and reflect the balance of incoming light. The most common beamsplitter ratio is 50/50 but we offer a variety of beamsplitter ratios for various wavelengths.

Our CaF2 beamsplitter offering excelent perfomance in 2-8 microns range. The CVD laser quality ZnSe beamsplitter provides a 50/50 ratio from 7 to 14microns. Other substrates for beamsplitter coating - Fused Silica, BK7, ZnS, NaCl, KCl - works in visible or infrared. Ask our sales team for specifications!
